E.ON Next: Business Energy Supplier Review

• Businesses that want renewable electricity as standard. E.ON Next's REGO-backed renewable option sits on selected tariffs rather than running through its whole range. If a wind-backed supply as the default matters to you, Scottish Power or Octopus are worth comparing, as we cover in our E.ON Next vs Scottish Power and Octopus vs E.ON Next guides.

• Very large or multi-megawatt energy users. E.ON Next's Large and Corporate Solutions tier exists, but businesses with high or complex consumption, multi-megawatt sites, half-hourly settlement across dozens of locations, typically get sharper terms through a specialist flexible procurement route than a tiered retail product.

• Businesses that want dynamic or time-of-use tariffs. E.ON Next's core business range is built around fixed pricing rather than half-hourly or time-of-use products. If your business can shift consumption away from peak hours, a supplier with a dedicated smart tariff range will usually reward that flexibility more directly.

• Businesses uneasy about the npower legacy. In our experience speaking with business owners, this comes up more than any pricing or product concern. It's worth judging E.ON Next on its current Kraken-based platform and independent scores rather than on npower's reputation from before 2021, since the two run on different infrastructure.

The Business Tariffs E.ON Next Offers

E.ON Next tiers its business tariffs by how much energy a business uses, rather than offering one universal product. As of 2026, the main options are:

SME Fixed Tariff. For businesses that meet the Ofgem or EU definition of a micro or small business, broadly those using 100,000 kWh or less of electricity a year and/or 293,000 kWh or less of gas. Prices are locked in for the length of the agreement, with a single fixed unit rate and standing charge and no separately reviewed elements.

Multi-Site and Property Tariff. A dedicated quote route for anyone managing two or more premises, or acting on behalf of another business as a property manager or landlord, with consumption and billing handled through one online account.

Large and Corporate Solutions. For businesses using more than 100,000 kWh of electricity a year and/or 293,000 kWh of gas, with bespoke pricing and support from a dedicated energy specialist rather than an online-only quote.

Renewable Electricity Tariffs. REGO-backed renewable electricity, available on selected business tariffs, giving businesses a way to evidence a renewable supply without moving to a specialist green supplier.

It's worth noting what E.ON Next doesn't offer as standard: there's no widely marketed half-hourly, time-of-use or dynamic pricing product for SMEs in the way Octopus's Shape Shifters range works. If shifting consumption away from peak hours is central to how your business runs, that's the clearest gap in E.ON Next's current line-up.

E.ON Next's Business Contract Terms

E.ON Next's fixed business contracts run for 1, 2 or 3 years, whether you're on the SME tariff or a bespoke corporate agreement. There's no fixed-term flexible or agile product in the way some newer entrants offer; if you don't renew at the end of your fixed term, your account moves onto a standard variable rate rather than losing supply.

As with every supplier, it's worth avoiding a lapse onto that variable rate regardless of who you're with. Our guide to pass-through and fully fixed energy contracts and our deemed and out-of-contract rates guide both explain why these default rates are consistently among the most expensive on the market, and what to do if you've already been moved onto one.

E.ON Next Business Prices

Because business energy isn't price-capped and E.ON Next doesn't publish one universal rate card, published figures are indicative rather than guaranteed. Based on current market pricing data, one industry pricing guide reported E.ON Next SME electricity unit rates for businesses using under 50,000 kWh a year running at roughly 23p to 26p per kWh, as of May 2026. Your own quote will depend on your postcode, meter type, usage band, contract length and credit profile.

A few things worth knowing before you compare a quote against that range:

The all-in fixed structure is E.ON Next's clearest pricing advantage. Unlike suppliers that fix the wholesale energy element but review network, social or environmental costs quarterly, E.ON Next's SME fixed tariffs are marketed as a single, fixed unit rate and standing charge for the whole contract. When we speak to business owners switching suppliers, this is consistently the detail that matters most, since it removes the risk of a quietly rising bill mid-contract even while the headline rate stays the same.

Exit fees apply on fixed contracts. As of July 2026, these are reported at £25 to £100, and E.ON Next is required to disclose the exact figure at sign-up.

Deemed and out-of-contract rates cost significantly more. If a fixed contract lapses without a renewal, your account moves onto a standard variable tariff that's rarely competitive. Use our business energy calculator to work out your actual usage before requesting quotes, so you can compare like for like rather than against an estimate.

How E.ON Next Backs Up its Sustainability Claims

E.ON Next's renewable electricity on selected business tariffs is backed by REGO (Renewable Energy Guarantee of Origin) certificates, the same mechanism most large UK suppliers use for green claims. It's worth understanding what that does and doesn't mean in practice. REGO-backed supply guarantees that renewable generation equivalent to your usage exists somewhere on the grid over the course of a year. It doesn't mean the electrons reaching your meter came directly from a wind farm at the moment you switched your equipment on.

One detail that sets E.ON Next apart from some competitors: it publishes a single fuel mix disclosure covering residential, small business and corporate customers together, under the same E.ON Next licence, rather than issuing a separate breakdown for business supply. That's useful for transparency, but it also means the published mix reflects the whole customer book rather than your specific tariff. If you need a fuel mix figure for ESG reporting, it's worth requesting the current disclosure directly from E.ON Next rather than relying on a domestic-facing summary from a comparison site.

Where E.ON Next differs from Scottish Power and Octopus is in how far renewable cover extends across its range. Both of those suppliers build renewable electricity into their standard business tariffs; E.ON Next offers it on selected tariffs rather than as the default. For an SME that wants a simple, no-extra-cost REGO-backed option, that's still a useful middle ground. For a business that needs green supply built into every product it might choose, it's worth checking the specific tariff before assuming it's covered.

What Real Businesses Say About E.ON Next

This is where E.ON Next's post-npower reputation looks different to its pre-2021 one, across every independent measure we checked.

Trustpilot. E.ON Next holds a rating of around 4.5 out of 5 from over 220,000 reviews, as of August 2026, one of the strongest scores of any UK Big Six supplier. Reviewers commonly praise polite, efficient customer service staff and clear communication during switches. The more critical reviews tend to focus on app functionality and meter reading processes, with some customers reporting they still need to phone in readings when the app doesn't sync correctly.

Citizens Advice. For the January to March 2026 period, E.ON Next scored 3.71 out of 5, placing it among the top three rated suppliers overall (behind only 100Green and Outfox Energy) and one of the strongest performers among the Big Six. Its previous quarter (October to December 2025) also placed it among the best-performing Big Six suppliers alongside Octopus, with the charity specifically noting strong performance on billing accuracy and smart meter functionality.

The honest summary. E.ON Next isn't flawless on every single measure, and the occasional poor review exists, as it does for every supplier. But across both Trustpilot and Citizens Advice, two independent sources measuring different things, it comes out consistently near the top of the Big Six rather than strong on one metric and weak on the rest. In our experience, that's the more meaningful signal than any single headline score, and it's a marked shift from the reputation npower carried before the migration.

Smart Meters, Apps and Business Tools

E.ON Next installs smart meters as standard across new business contracts, run through the same Kraken-based platform used across its residential book. Beyond metering, the wider toolkit for business customers includes:

• An online account and app covering meter readings, billing, contract renewal and usage data.

• A digital energy insights dashboard, showing usage patterns and offering sustainability tips for businesses on compatible smart meters.

• Multi-site account management, letting businesses managing up to around 50 meters handle billing, renewals and switching from one place.

• EV charge point installation support for business premises and fleets.

• Dedicated energy specialists for larger and corporate accounts, alongside phone, WhatsApp and live chat support during business hours for smaller accounts.

E.ON Next for Business: Trade-Offs at a Glance

Switching to E.ON Next, Step by Step

1. Get a quote. You'll need your business address and postcode, your estimated annual consumption from a recent bill, and ideally your MPAN (electricity) or MPRN (gas) meter reference number.

2. Choose your tariff and contract length. E.ON Next will confirm which tier applies (SME Fixed, Multi-Site, or Large and Corporate) based on your usage.

3. Tell your current supplier you're leaving. E.ON Next typically handles the notification for you as part of a standard switch, but check this at sign-up, particularly if you're on a bespoke corporate contract.

4. Sign up, providing your company details and payment information.

5. Receive your welcome pack, including your rates, supply start date and full terms and conditions.

6. Provide a meter reading around your switchover date, or have your new smart meter installed if your premises doesn't already have one.

7. Your account is billed on your agreed cycle once supply begins, settled by Direct Debit in most cases.

Exit Fees and Ending Your Contract Early

Exit fees apply on fixed business contracts, typically £25 to £100 as of July 2026. E.ON Next is required to disclose the exact figure for your tariff at sign-up.

If you do nothing at contract end, you're moved onto a standard variable rate rather than losing supply. This protects continuity but rarely offers the best price, so it's worth actioning a renewal or switch decision before your end date rather than after it.

If you're moving premises, notify E.ON Next as early as possible. As with most suppliers, failing to arrange continued supply at your new address can leave your existing contract cancelled from your move-out date.

Leaving E.ON Next to Switch Suppliers

Leaving E.ON Next works the same way as leaving any UK business energy supplier:

1. Get quotes from other suppliers before your current contract ends, ideally starting your comparison in the 90 days before renewal.

2. Check your exit fee, and weigh it against any savings a new contract would deliver.

3. Confirm the switch with your new supplier, who will typically handle notifying E.ON Next on your behalf.

4. Give a final meter reading on your last day of supply to ensure an accurate closing bill.

5. Settle your final account. Chase any outstanding credit if it doesn't land within a few weeks of your contract closing.

Why Compare Before You Commit?

E.ON Next is a solid supplier by most independent measures, but 'solid' isn't the same as 'cheapest for your specific business', and the two don't always line up. Rates depend on your postcode, usage band, meter type and contract length, all of which shift the answer from one business to the next.

That's exactly what comparing properly solves. Tell us your postcode, estimated usage and current contract end date, and we'll compare live quotes across our panel of suppliers, E.ON Next included, rather than asking you to chase individual quotes yourself. Start with our free business energy calculator tool if you're not sure of your usage, or read our guide to finding the best business energy supplier if you're comparing more broadly across the market.

E.ON Next Business FAQs

Is E.ON Next good for business electricity?

Yes. It combines a fully fixed pricing structure, consistently strong independent service scores on Trustpilot and Citizens Advice, and a straightforward REGO-backed renewable option. It's a weaker fit if you want green electricity built into every tariff as standard, or if you're a very large, complex energy user better served by specialist procurement.

Is E.ON the same as npower?

No. E.ON Next was built as a new brand following E.ON's 2019 acquisition of npower's parent company, Innogy. Around two million former npower customers were migrated onto E.ON Next's current Kraken-based platform by May 2021, and the npower brand now only survives for larger commercial customers under npower Business Solutions, a separate entity.

Is E.ON Next part of the Big Six?

Yes. Under the current market-share definition, the Big Six are Octopus Energy, British Gas, E.ON Next, OVO Energy, EDF Energy and ScottishPower.

Does E.ON Next charge exit fees for business customers?

Yes. As of July 2026, exit fees are reported at £25 to £100, and E.ON Next is required to disclose the exact figure at sign-up.

What happens if I don't renew my E.ON Next business contract?

You're automatically moved onto a standard variable rate rather than losing supply. This avoids disruption, but variable rates are rarely the cheapest option available, so it's worth renewing or switching ahead of your end date.

Is E.ON Next's business electricity renewable?

Yes, on select tariffs. It isn't standard across E.ON Next's whole business range, so check the specific tariff you're quoted rather than assuming green cover applies by default.

How do I get a business energy quote from E.ON Next?

SME businesses can get an online quote directly through E.ON Next using their postcode and estimated annual consumption. Larger or multi-site businesses are usually routed to a dedicated energy specialist. You can also compare E.ON Next alongside other suppliers using BusinessComparison to see how it stacks up before you commit.

Our Verdict: Should You Switch?

Best for: SMEs that want fixed, predictable pricing and a supplier with a strong, consistent reputation, particularly businesses that were migrated from npower and haven't reassessed the supplier since.

Think twice if: you want renewable electricity built into your tariff as standard rather than on selected products, you need a time-of-use or half-hourly tariff to reward flexible consumption, or you're a large, complex energy user better served by bespoke flexible procurement.

E.ON Next has done more than most suppliers to shed a difficult inherited reputation, and the independent data backs that up: a top-three Citizens Advice Star Rating and a Trustpilot score above 4.5, both a meaningful distance from where npower sat before the 2021 migration. For the typical SME, it's a strong candidate, particularly if a fully fixed, no-surprises contract matters more to you than a supplier with the deepest green credentials.

It isn't automatically the cheapest option for your specific business, and its product range is narrower than some competitors if you want dynamic pricing or a wind-backed tariff as standard. The right move is the same one we'd recommend before signing with any supplier: compare your actual quote against the rest of the market, check the tariff terms against how your business actually uses energy, and don't let an improved reputation substitute for checking the numbers.
